Handling logs by electric motocylinders

FOR YEARS sawmills have used various forms of specialized machinery to produce reciprocating and oscillating motions for log and timber-handling operations. Until recently this machinery was powered by steam (air) cylinder and piston, simple devices well suited to the applications, being fast, powerful, of low cost, and of rugged construction, an essential service requirement. Sawmill waste was used to generate the mill´s total steam and power requirements.
